Potential of GNSS Post Processing Kinematic (PPK) Technique for Test Range Surveying Applications using Compact, Low Cost GNSS Modules

Abstract

The evolution of multiple global and regional GNSS constellations over the last two decades has transformed the positioning, navigation, and timing (PNT) technology unprecedently by introducing an unmatched combination of precision, accuracy, convenience, and confidence. Various methods and techniques like use of dual frequency, ionospheric error-free standard positioning service (SPP/SPS), real time kinematic (RTK), and precise point positioning (PPP) have increased the level of accuracies and precision in both static and dynamic operations. This study explores the potential of dual frequency Post Processing Kinematic (PPK) RTK positioning for test range applications using compact, low cost, dual frequency (CLD), multi-constellation GNSS modules. The results show centimeter-level solution accuracy; the results would be useful in enhancing the confidence of using such systems for various applications where real time wireless connectivity between the Base and Rover is not available, or in cases where the real time connectivity between the RTK Base and Rover poses cyber security threats.
